Active clinical trials for "Urinary Bladder Neoplasms"

Background: - The drugs FdCyd (also called 5-fluoro-2'-deoxycytidine) and THU (also called tetrahydrouridine) are being used in a cancer treatment study. Not a lot is known about how FdCyd works in the body. Researchers want to look at a modified form of FdCyd using imaging studies to see how the drug reacts with the cancer. This study is not a treatment study. It is open only to people who are already on the FdCyd and THU cancer treatment study. Objectives: - To study how FdCyd affects advanced cancer cells. Eligibility: - Participants in National Cancer Institute study 09-C-0214. Design: Participants will have two imaging studies, one before starting FdCyd and THU treatment and one after starting treatment. Participants will have the modified FdCyd, known as F-18 FdCyd, with a dose of THU. The doses will be followed by two imaging study scans and frequent blood samples. This procedure will be repeated at a later date, during the FdCyd and THU treatment period. Treatment will not be provided as part of this study. This is an imaging study protocol only....

This is a single-center, prospective, randomized, controlled trial comparing two established transurethral electrical resection methods of urinary bladder tumors regarding their risk of stimulating the obturator nerve. One of the major safety issues with transurethral resection is bladder perforation as a consequence of obturator nerve stimulation followed by muscle contraction of. This is mostly a risk of resection of lateral bladder wall tumors near the course of the obturator nerve. It has been advocated that bipolar may be superior to monopolar resection, based on its different electrical properties. This is an important safety aspect for the patient. Main study question: In patients with lateral wall urinary bladder tumors, is bipolar superior to monopolar transurethral electroresection regarding risk of stimulation of the obturator nerve without preoperative nerve block?

Primary objective: To assess the early signals for anti-tumor activity (i.e. objective response rate, progression-free survival) of pembrolizumab in combination with vorinostat in patients with advanced prostate, renal or urothelial cell carcinoma. Secondary objectives: (1) To evaluate the overall safety profile of pembrolizumab in combination with vorinostat; (2) To assess the safety and tolerability of pembrolizumab in combination with vorinostat in patients with advanced prostate, renal or urothelial cell carcinoma in order to select the recommended Phase 2 Dose (RP2D); (3) To characterize immune cell subsets, and miRs in tumor and/or blood.

Conventionally, transurethral standard resection (SR) of bladder tumour is performed in a piecemeal manner. Transurethral en bloc resection (EBR) has been described as an alternate surgical technique in bladder tumour resection. By preventing tumour fragmentation and ascertaining complete tumour resection by histological assessment of the EBR specimen, we hypothesized that EBR could reduce disease recurrence as compared to SR.

This is a multi-center Phase II study to determine the safety and efficacy of nivolumab when given in combination with cisplatin and gemcitabine as neoadjuvant treatment in patients with muscle-invasive bladder cancer (MIBC) prior to standard of care radical cystectomy. Patients will receive neoadjuvant treatment with nivolumab in combination with gemcitabine-cisplatin (GC) every 3 weeks for 4 treatment cycles over 12 weeks followed by standard of care radical cystectomy.

This is a multi-institutional, randomized, placebo controlled, double-blinded phase II trial of maintenance pembrolizumab versus placebo after first-line chemotherapy in patients with metastatic urothelial cancer who have achieved at least stable disease on first-line chemotherapy.

Laser treatment of pTa low grade bladder tumours in the outpatient department Number of Subjects/Centres Planned: 20 patients will be included in this study. The study will be performed at Department of Urology, Bispebjerg-Frederiksberg Hospital, Copenhagen, Denmark. Primary Objective: To show that small pTa bladder tumours safely can be removed with diode laser in an outpatient department Secondary Objective: To evaluate the patients experience with the laser treatment using QOL questionaires (symptom evaluation) and Visual Analog Scale Score (pain evaluation).

Phase 1 study to provide quantitative characterization of the renal elimination of ethacrynic acid and metabolites in patients with non-muscle invasive bladder cancer (NMIBC) at the time of transurethral resection of bladder tumor

A multi center, open-label, Phase 1 dose escalation study with expansion cohort is designed to determine the MTD, RP2D and dosing schedule of PRS-343 in patients with HER2+ advanced or metastatic solid tumors.

The purpose of the study is to increase the radiation dose (Boost) to the bladder tumor. The bladder cancer patients included in the study will undergo tumor demarcation. The bladder demarcations will then be the target for an image-guided boost delivered precisely to the expected tumor site.
